Hey all,

Just need help pulling the trigger.

Im upgrading my fuel pump and injectors to run e85.

Ive read through the E85 thread but just need some advice pulling the trigger.

Im aiming for around 400kws in my 33 GTR.

Im going to use the intank walbro E85 pump, should be big enough?

The injectors im deciding between the

BOSCH EV14 1000cc + 11mm Extensions + Plugs

or the

BOSCH 2200cc Injectors + 11mm Extensions + Plugs

Will 1000cc be big enough? ive been told buy the sales team of the place im getting them for they should be?

Or for an extra $200 go the 2200cc injectors. But reading have said they arent as easy to tune or something?

Any advice or real world knowlage of these two in your own cars would be great

thanks

Adam

You need at least 740cc injectors to support that sort of power on 98. Given that e85 needs more than 50% extra injector capacity to be safe, then 1000cc injectors is actually a bit on the slim side. I'd be looking at something bigger, but not as big as the 2200s. There's ID1300 and so on available, yes?

Ok thats what i was thinking, just getting myself confused...

Does that go for the stainless insides of the 1300cc boschs?

Is there really that much of a differance between the standard bosch and the ids?

The ID2000 spray pattern is pretty poor and linearization becomes a problem below 1.4ms pulse width. This causes all sorts of issues with E85 from poor idle control, poor engine response to cylinder bore washing. They work but users need to understand the additonal risk...fuel dilution etc

It is my understanding that any of these Bosch EV14s need to be modified for use on liquid fuels, as they are originally gas injectors. I might be wrong, but that was my understanding.

The 1000's are fine, the 2000's are natural gas injectors.

If ID actually release the 1300's for sale (I hear they are having issues supplying them atm) they would be the best option, until then the 1000's are your best choice, with a higher base fuel pressure to bump them up into the 1300-1500cc flow area. Be wary buying from the US as a warranty from there is almost useless. (by the time you pay for shipping back to ID and wait a month for them to be returned.)

The other option is Moran injectors, not cheap but there are plenty of sizes to chose from, and they spray beautifully, but you will need a 10 micron filter for them or your warranty is void.

Any other options for slightly bigger as those morans are damn expensive

Not for E85, there are 2200cc continental/VDO injectors for petrol vehicles, but I have never seen them used, and they are a little more expensive than the Bosch 2000's last I checked with my wholesaler.

The moran injector fan/spray angle is very wide... I allways wondered if you'd get to much wetting down against the intake mani wall.

Ever seen a set in a GTR?

Not yet, the EV14's are the big seller, the Morans are always too expensive at around $250-$300 each, depending on size.

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks

      M35 VQ25DET starter motor

      By iain_ST44GA · Posted

      Hi Guys, Does anyone know any aftermarket part numbers for a starter motor to suit the VQ25DET? I can find lots of alternative part number for the VQ35DE, which I assume would fit, but there is a lot of conflicting information out there. Thanks..
